Answer:
70%
Step-by-step explanation:
Maths homework takes 1/6×150mins
=150/6=25 mins
science homework takes 20/100×150
=3000/100
=30mins
Language Arts homework uses 1/3×150
=150/3
=50 mins
percent of time left for Marsha's social studies homework=total time used / original time
=(25+30+50)mins
=105mins/150mins×100%
=0.7×100
=70%
Using the formula for the nth term of an arithmetic sequence we can write:
80 + (n - 1)2 = 65 + (n - 1)5
80 + 2n - 2 = 65 + 5n - 5
3n = 18
n = 6
The answer is 6 months.
